USB to Serial
The device's USB connector can also be used as a serial port.
Field | Value | Description |
---|---|---|
Enabled | off | on; default: off | Turns the USB to Serial service on or off. |
Baud rate | 300 | 1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600 | 115200; default: 115200 | Data rate for serial data transmission (in bits per second). |
Data bits | 5 | 6 | 7 | 8; default: 8 | Number of data bits for each character |
Parity | None | Odd | Even; default: None | In serial transmission, parity is a method of detecting errors. An extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check.
|
Stop bits | 1 | 2; default: 1 | Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used. |
Flow control | None | RTS/CTS | Xon/Xoff; default: None | In many circumstances a transmitter might be able to send data faster than the receiver is able to process it. To cope with this, serial lines often incorporate a "handshaking" method, usually distinguished between hardware and software handshaking.
|
Serial type | Console | Over IP | Modbus gateway | NTRIP client; default: Console | Specifies the serial connection type. Look to the sections below for information on different USB to Serial type options. |
Console
Console mode requires no further configuration than the settings above and is used as a direct-access method to the device's shell interface. For this purpose you may want use such applications as PuTTY on Windows and microcom, minicom, picocom or similar applications on Linux.
Over IP
The Over IP serial type is used to manage serial connections over a TCP/IP network.
Field | Value | Description |
---|---|---|
Protocol | TCP | UDP; default: TCP | Protocol used in the communication process. |
Mode | Server | Client | Bidirect; default: Server | This device's role in the connection:
|
No leading zeros | off | on; default: off | When checked, indicates that the first hex zeros should be skipped. |
Server settings: Port | integer [0..65535]; default: none | Internal port number used to listen for incoming connections. |
Server settings: Timeout (s) | integer; default: none | Specifies an inactivity time limit (in second) after which an inactive clients is disconnected. |
Server settings: Open port automatically | off | on; default: on | Automatically adds a traffic rule in the firewall configuration to open the required port for NTRIP communication. |
Client settings: Server Address | ip | host; default: none | IP address or hostname of the server that this client will connect to. |
Client settings: Port | integer [0..65535]; default: none | Server's listening port number. |
Client settings: Reconnect interval (s) | integer; default: none | Time period (in seconds) between reconnection attempts in case a connection fails. |
Echo | off | on; default: off | Turn USB to serial echo on or off. |
Modbus gateway
The Modbus gateway serial type allows redirecting TCP data coming to a specified port to an RTU specified by the Slave ID. The Slave ID can be specified by the user or be obtained directly from the Modbus header.
Field | Value | Description |
---|---|---|
Listening IP | ip; default: 0.0.0.0 | IP address to listen for incoming connections. The default value (0.0.0.0) means that this device will listen for incoming connections on any interface or IP address. |
Port | integer [0..65535]; default: 502 | Port number to listen for incoming connections. |
Slave ID configuration type | User defined | Obtained from TCP; default: User defined |
Specifies whether slave IDs are user defined or automatically obtained from TCP. |
Slave ID | Permitted slave IDs | integer | range of integers; default: 1 or 1-247 |
Specifies the slave ID of range of permitted slave IDs. The way this field is named and its function depends on the value of the Slave ID configuration field. A range of IDs can be specified by placing a hyphen (-) between two integer numbers. For example, if you permit slave IDs in the range of 10 to 20, you would specify it as: 10-20 You can also specify multiple values that are not connected in a range using commas (,). For example, to specify 6, 50 and 100 as permitted slave IDs, you would have to use: 6,50,100 |
Open port automatically | off | on; default: on | Automatically adds a traffic rule in the firewall configuration to open the required port for serial communication. Caution: use with care if listening IP is left as the default value (0.0.0.0). Leaving it as such will leave the device open for remote connections on the specified port. |
Echo | off | on; default: off | Turn USB to serial echo on or off. |
NTRIP client
Networked Transport of RTCM via Internet Protocol (NTRIP) is a protocol for streaming differential GPS (DGPS) data over the Internet in accordance with specification published by RTCM.
Field | Value | Description |
---|---|---|

Use device GPS | off | on; default: off | Allows to obtain default NMEA string from the router's GPS device. Only works if GPS service is enabled and location fix is obtained at the time of NTRIP service start. |
Open port automatically | off | on; default: on | Automatically adds a traffic rule in the firewall configuration to open the required port for serial communication. |
Echo | off | on; default: off | Turn USB to serial echo on or off. |
Storage Memory Expansion
The Storage Memory Expansion function provides the possibility to expand the device's flash memory with a USB Mass Storage Device (MSD) and use the extra memory to install additional software packages. This section provides instruction on how to do just that. However, there are a few prerequisites and warnings to take note of before using memory expansion.
To be eligible for memory expansion, the USB MSD must meet the following restrictions.
- The MSD must be the last one (chronologically) inserted.
- If you are using a USB hub, the target MSD must be the last one attached to the hub.
- No important data on the MSD as it will be wiped during expansion setup!
When expansion is enabled, do not detach the USB device as this will delete the data stored on it. Changes made to the device configuration while expansion was enabled will disappear after it is disabled.
Enabling memory expansion
To successfully expand the flash memory of your device follow the steps described below.
- Attach a USB Mass Storage Device (MSD) to the USB connector on the device and go to the Services → Storage Memory Expansion page.
- Set the 'Enable storage expansion' slider to 'on' and click 'Save & Apply'.
- You will see a pop-up asking for confirmation. Take note that if you continue from this point on:
- your USB device's memory will be wiped and formatted to ext2 format;
- your device's current configuration will be backed up and restored to this point if the USB drive is removed or memory expansion is disabled;
- the entire procedure may take a very long time and includes a reboot at the end; exact time will vary depending on the size of the MSD (larger size will take longer; for example, using a 128 GB drive will take about 2 hours to fully set up, while a 16 GB will only take about 5 minutes).
- If all is in order you should see a 'Formatting MSD...' message on the screen. This indicates that the MSD is being formatted and integrated with the system. This procedure can take a long time and ends with a reboot of the device.
- Your device's flash memory will be expanded once the reboot has finished. In order to check, log in to the WebUI and look to the 'System' widget in the 'Overview' page. Hover your mouse cursor over the 'FLASH' memory indicator; you should see an increase to the device's flash memory.
Disabling memory expansion
To successfully disable memory expansion follow the steps described below.
- Go to the Services → Storage Memory Expansion page.
- Set the 'Enable storage expansion' slider to 'off' and click 'Save & Apply'.
- You will see a pop-up asking for confirmation. Take note that if you continue from this point on:
- your USB device's memory will be wiped and formatted to NTFS format;
- your device's configuration will be restored to the point it was before memory expansion;
- the entire procedure will take up to 2 minutes including a reboot.
- If all is in order you should see a 'Formatting MSD...' message on the screen. This indicates that the MSD is being formatted and detached from the system. This procedure can take up to a couple of minutes and ends with a reboot of the device.
- Your device's flash memory will be restored to normal once the reboot has finished. In order to check, log in to the WebUI and look to the 'System' widget in the 'Overview' page. Hover your mouse cursor over the 'FLASH' memory indicator; you should see your device's flash memory return to its regular size.
The Network Shares section is used to manage Network-attached storage (NAS) such as USB drives and hard drives. The {{{name}}} device supports the following file system architectures:
- FAT
- FAT32
- NTFS
General Settings
The General section is used to set up Samba - a software solution for using the Server Message Block (SMB) networking protocol, which provides shared file access between nodes on a computer network. Refer to the figures and table below for more information about Samba configuration.
Field | Value | Description |
---|---|---|
Enable | off | on; default: off | Turns Samba on or off. |
Hostname | string; default: Router_share | Name of the Samba server. |

Workgroup | string; default: WORKGROUP | Name of the server's workgroup. |
Share home-directories | off | on; default: on | Allows system users to reach their home directories via network shares. |
Edit Template
The Edit Template section is used to make modifications to the template that is used for generating the Samba configuration. This is the content of the /etc/samba/smb.conf.template file from which your Samba configuration will be generated. Values enclosed by pipe symbols ('|') should not be changed. They get their values from the 'General Settings' tab.
Format USB
The Format USB section contains only one button that is used for formatting an attached USB drive.
The Shared Directories section is used to configure access to the device's files and directories, including USB storage drives. The list of Shared Directories is empty by default; click the 'Add' button in order to create a new configuration:
The newly added Shared Directory configuration should look similar to this:
Field | Value | Description |
---|---|---|
Name | string; default: none | Name of a shared directory. |
Path | filepath; default: /mnt/ | Path to a shared directory. To share an entire drive, choose an automatically generated path from this drop-down box (for example, /mnt/sda1). To share a specific directory on the drive, specify the full path to that directory (for example, /mnt/sda1/shared/video). |
Allowed users | samba user(s); default: none | Samba user(s) that are permitted to access a shared directory. Users can be created from the Users menu tab. |
Read-only | off | on; default: off | Makes a directory read-only, which means the shared directory can only be accessed to view and read files. |
Browseable | off | on; default: on | Makes a Shared Directory browsable; i.e., visible in network shared directory discovery. |
Allow guests | off | on; default: off | Turns guest access on or off. Guest access allows anonymous connections to a Shared Directory. |
Delete | -(interactive button) | Deletes a Shared Directory configuration. |
To connect to the router's SAMBA server from Windows, specify the address in this format:
\\smb_server_address\share_name
Replace smb_server_address with the IP address of this device or SAMBA share hostname; replace share_name with the name of the "share" (as specified in the 'Name' field). For example:
\\192.168.1.1\my_share \\Router_share\johns_files
Users
The Users section is used to create Samba users that can be granted access to Shared Directories. To add a new user, enter a custom username, password and click the 'Add' button.
The newly added User should appear in the Users list. To change the password of a Samba User, click the 'Edit' button located next to it:
This will redirect you to the Settings page for that User which should look similar to this:
